The Recipe
Set the oven at 220C/gas mark 7. Whisk together 2 eggs and 300ml of full-fat milk. Add a good pinch of salt, then beat in 125g plain flour. Heat 3 tbsp of lard or dripping in a small roasting tin or baking dish until it starts to smoke. Add 6 fat pork sausages and let them colour on all sides then, while the oil and sausages are smoking hot, pour in the batter. Bake for 25-30 minutes until puffed and golden.
The Trick
Like making Yorkshire pudding, get the fat in the roasting tin (literally) smoking hot before adding the batter. I put the lightly cooked sausages in the pan first then pour in the batter when you can see a blue haze rising. I am a great believer in letting the batter rest before using, though others disagree.
The Twist
Nigella's adorable new book Kitchen (Chatto and Windus, £26) turns the toad on its head by using sausage patties, the meat pressed from its casing and shaped into tiny burgers. Delightful, especially if you season them with thyme. I often wrap my sausages, minus their skins, in very thin bacon or pancetta. Onion gravy is the usual accompaniment, but new thinking involves hot, rough-textured tomato sauce or even a creamy mustard one, such as you might serve with rabbit.
